Perihilar cholangiocarcinoma (pCC, also known as a Klatskin tumor) is the most common type of cholangiocarcinoma (CC). Preoperative biliary drainage (PBD) is indicated for pCC patients with acute cholangitis or patients who need portal vein embolization (PVE). However, the routine performance of PBD in other patients with pCC is still controversial. The current study retrospectively examined patients with pCC who did not undergo PVE and who did not have cholangitis who were seen at this Hospital to assess the advantages and disadvantages of PBD...

In this issue of Radiology, Gade et al ( 1 ) describe a unique mechanism of hepatocellular carcinoma (HCC) cells for surviving ischemia induced by transarterial embolization (TAE)/transarterial chemoembolization (TACE) in a state of cell cycle arrest-a function that may serve as a defensive shield against conventional chemotherapeutic agents. This finding adds to our knowledge and establishes a previously poorly understood mechanism of chemoresistance in HCC. As the Achilles heel in terms of this process, a concurrent upregulation of autophagic flux as an adaptive response to TAE-like ischemia was found by the authors...

BACKGROUND: Superior vena cava (SVC) syndrome is a major complication that occurs when a growing lung malignancy compresses the SVC extrinsically. Current treatment options include radiotherapy or chemotherapy to shrink the tumor or endovascular stenting of the SVC to restore flow. Herein, we report a case series treated in a single institution to demonstrate the safety, effectiveness, and outcomes of salvage and primary stenting for malignant SVC obstruction. METHODS: A total of 12 male patients with malignant superior vena cava obstruction caused by lung cancer underwent SVC stenting from October 2009 to May 2015...

Transarterial radioembolization (TARE) with yttrium 90 (90Y), an intra-arterial procedure performed by interventional radiologists, has begun being utilized in managing hepatocellular carcinoma (HCC) in Korea. There are two available TARE products: glass and resin microspheres with different physical characteristics. All patients undergoing TARE must be assessed with clinical examination and laboratory tests as well as a thorough angiographic evaluation. TARE is safe and effective in the treatment of unresectable HCC, as it has longer time-to-progression, greater ability to downsize tumors for liver transplantation, less post-embolization syndrome, and shorter hospitalization compared with chemoembolization...

Interventional radiology plays a major role in the modern management of liver cancers, in primary hepatic malignancies or metastases and in palliative or curative situations. Radiological treatments are divided in two categories based on their approach: endovascular treatment and direct transcapsular access. Endovascular treatments include mainly three applications: transarterial chemoembolization (TACE), transarterial radioembolization (TARE) and portal vein embolization (PVE). TACE and TARE share an endovascular arterial approach, consisting of a selective catheterization of the hepatic artery or its branches...

Stereotactic body radiation therapy (SBRT) is delivered in a curative intent to many primary and secondary tumors. Concerning liver metastasis, SBRT can be safely delivered using one to five fractions. An excellent local control is obtained with doses from 20 to 60 Gy. For primary hepatic tumors, results are also good, but the risk of hepatic toxicity related to liver pre-existent pathology must be taken into account. Radiation induced liver disease (RILD) is not frequent in its classical presentation, but modifications of liver enzymes are often observed...

BACKGROUND: Cardiac myxoma is known to cause repeated events of cerebral embolism. Soft and irregularly shaped myxomas with high mobility are associated with a higher occurrence of cerebral embolism. In contrast, nonmobile cardiac myxomas with a round regular shape are rarely considered to be a cause of cerebral embolism. In this case, we present a patient with recurrent cerebral embolism associated with a small and nonmobile cardiac myxoma of round regular shape. CASE PRESENTATION: A 76-year-old Japanese man presented to our hospital with weakness in his right upper extremity...
